obtain from crude Tartar, store of a very Volatile and Crystalline Salt, differing very much in smell and other Qualities from the usuall salts of Tartar.
But (sayes Eleutherius, interrupting him at these Words) if you have no restraint upon you, I would very gladly before you go any further, be more particularly inform’d, how you make this Volatile Salt, because (you know) that such Multitudes of Chymists have by a scarce imaginable Variety of wayes, attempted in Vain the Volatilization of the Salt of Tartar, that divers learned Spagyrists speak as if it were impossible, to make any thing out of Tartar, that shall be Volatile in a Saline Forme, or as some of them express it, in forma sicca. I am very farr from thinking (answers Carneades) that the Salt I have mention’d is that which Paracelsus and Helmont mean when they speak of Sal Tartari Volatile, and ascribe such great things to it. For the Salt I speak of falls extreamly short of those Virtues, not seeming in its Tast, Smel, and other Obvious Qualities, to differ very much (though something it do differ) from Salt of Harts-horn, and other Volatile Salts drawn from the Distill’d Parts of Animals. Nor have I yet made Tryals enough to be sure, that it is a pure Salt of Tartar without participating any thing at all of the Nitre, or Antimony. But because it seems more likely to proceed from the Tartar, than from any of the other Ingredients, and because the Experiment is in it self not Ignoble, and Luciferous enough (as shewing a new way to produce a Volatile Salt contrary to Acid Salts from Bodies that otherwise are Observ’d to yield no such Liquor, but either only, or chiefly, Acid ones,) I shall, to satisfie you, acquaint you before any of my other Friends with the way I now use (for I have formerly us’d some others) to make it.
Take then of good Antimony, Salt-Petre and Tartar, of each an equal weight, and of Quicklime Halfe the Weight of any one of them; let these be powder’d and well mingl’d; this done, you must have in readiness a long neck or Retort of Earth, which must be plac’d in a Furnace for a naked Fire, and have at the top of it a hole of a convenient Bigness, at
